TECHNICAL FIELD

The present invention relates to a diazepine derivative having a P2X4receptor antagonist activity.

BACKGROUND ART

The ATP receptors are roughly classified into the P2X family of the ionchannel type receptors, and the P2Y family of the G protein couplingtype receptors, and seven kinds (P2X₁ to P2X₇) and eight kinds (P2Y₁,P2Y₂, P2Y₄, P2Y₆, and P2Y₁₁ to P2Y₁₄) of subtypes have so far beenreported, respectively.

The P2X4 receptor (Genebank No. X87763), a subtype of the P2X family,has been reported to be widely expressed in the central nervous system,and the like (Non-patent documents 1 to 5).

The onset mechanisms of intractable pains, including neurogenic pain,have not been precisely elucidated. If non-steroidal anti-inflammatorydrugs (NSAIDs) and morphine are not effective, no therapy is availablefor that pain. Therefore, very heavy physical and mental burden is givento patients and surrounding people. Neurogenic pain is often caused byinjury of a peripheral nerve or the central nerve, and it is caused by,for example, after trouble of operation, cancer, spinal cord injury,herpes zoster, diabetic neuritis, trigeminal neuralgia, and the like.

Recently, Inoue et al. verified the involvement of the P2X receptor inneurogenic pain by using a spinal nerve-damaged animal model in whichallodynia can be detected. The authors described that nerve-damaged typeunusual pain (especially allodynia) is induced through the P2 X 4receptor expressed in the microglia cells of the spinal cord (Non-patentdocuments 6 and 7, and Patent document 1).

Therefore, a substance that inhibits the activity of the P2X4 receptoris expected to be a prophylactic or therapeutic agent for pains ofnociceptive pain, inflammatory pain, and neurogenic pain.

Patent document 2 reported that a benzofuro-1,4-diazepin-2-onederivative represented by the following general formula (A):

(in the formula, R₁ is a halogen, and R₂ is hydrogen, a halogen, nitro,cyano, C(O)—OR₃, C(O)—NR₄R₅, SO₂—OR₃, or SO₂—NR₄R₅, or alternatively, R₁is hydrogen, and R₂ is a halogen, nitro, cyano, C(O)—OR₃, C(O)—NR₄R₅,SO₂—OR₃, or SO₂—NR₄R₅) has a P2X4 receptor antagonist activity.

It was also reported that paroxetine, which is an antidepressant, alsohas a P2X4 receptor antagonist activity (Non-patent document 8).

The inventors of the present invention also found that anaphtho[1,2-e]-1,4-diazepin-2-one derivative represented by thefollowing formula (B):

and related compounds thereof has a P2X4 receptor antagonist activity,and filed patent applications (Patent documents 3, 4 and 5).

The compounds of Patent documents 3 to 5 mentioned above and thecompounds of the present invention represented by the general formula(I) mentioned later are distinguishable from each other in that, in theformer compounds, the substituent of the phenyl group at the 5-positionis hydroxy group, a halogen atom, an alkyl group having 1 to 8 carbonatoms, tetrazolyl group, or the like, whereas, in the latter compounds,the phenyl group or the heterocyclic ring represented by G is bound viaNHC(═O), NHC(═O)NH, or NHS(O)₂ represented by B. In addition, althoughPatent documents 4 and 5 describe an acylamino group having 2 to 8carbon atoms and an acylamino group having 2 to 8 carbon atoms andsubstituted with 1 to 3 halogen atoms as the substituent of theaforementioned phenyl group, they only refer to lower alkylcarbonylaminogroups such as acetylamino and trifluoromethylcarbonylamino groups asspecific examples thereof, and do not describe benzoylamino groupwherein G is phenyl group, and B is NHC(O) and the like of the compoundsof the present invention represented by the general formula (I)mentioned later.

Further, Patent document 6 describes a naphtho[1,2-b]-1,4-diazepin-4-onederivative represented by the following formula (C):

However, although Patent document 6 describes that the compoundrepresented by the aforementioned formula (C) is used as a photographiccoupler, there is no description suggesting relation between such acompound and P2X4 receptor antagonist activity.

Further, Patent document 7 describes a 1,4-benzodiazepine derivativehaving a phosphodiesterase 2 inhibitory activity, which is representedby the formula (D):

However, this patent document does not describe that the compound of theformula (D) has a P2X4 inhibitory activity.

Hereafter, the pharmacological efficacies of the compounds of thepresent invention will be described.

The P2X4 receptor antagonist activity of the compounds of the presentinvention was measured as follows.

The ATP receptor (human P2X4) was introduced into the 1321N1 cells, andthe cells were used as a stable ATP receptor expression system. TheP2X4-expressing 1321N1 cells were inoculated on a 96-well plate,cultured under the conditions of 37° C. and 5% CO₂ for 24 hours, andused for calcium measurement. Fura-2 AM, which is a calcium fluorescentindicator, was dissolved in an extracellular fluid for calcium imaging,and the inoculated cells were treated with the solution, and leftstanding at room temperature for 45 minutes so that Fura-2 AM wasincorporated into the cells. For the measurement, a microplate reader,FLUOstar Optima (BMG Labtech), was used. The light emitted from a xenonlamp was passed through 340 nm and 380 nm filters, respectively, andirradiated on the cells, fluorescences of 510 nm, F340 and F380, emittedfrom the cells were measured, and change of the ratio F340/F880 was usedas an index of change of intracellular calcium level. The measurementwas performed by adding ATP to each well at a final concentration of 1μM, and observing the ATP-induced Ca^(2a) response over time. In themeasurement, a treatment with a test substance was performed 15 minutesbefore the addition of ATP, and the inhibition activity of the testsubstance was calculated by comparison of the result with the resultobtained in the absence of the test substance.

The analgesic activity of the compounds of the present invention wasmeasured by the following method.

Preparation of Neurogenic Pain Model (Modified Chung Model)

Neurogenic pain model (modified Chung model) was prepared according tothe description of Non-patent document 9. More specifically, underisoflurane anesthesia, back hair of rats was extensively shaved, theshaved parts were wiped with rubbing alcohol, the rate were fixed on anincubator in the abdominal position, and the skins were cut and openedalong the dorsal median line on the upper and lower sides of thesacroiliac bone. The left lateral paravertebral muscle was separated inthe sacral region, and then the ligament was separated. The sacroiliaerim and the upper part thereof were cut and opened along the pyramid,the L5 nerve was ligated, and the nerve was cut on the peripheral side.The operative wound was sutured, and infection was prevented byintraperitoneal injection of Luinesin after the operation.

The pain threshold value (paw withdrawal threshold (g)) was calculatedaccording to the up down method by stimulating the sole with a von Freyfilament (Stoelting Co., TOUCH-TEST SENSORY EVALUATOR) and determiningpresence or absence of withdrawal response. The rate that showed a 50%pain threshold value of 5 g or lower in the von Frey filament test weredetermined to have allodynia.

Up Down Method and Calculation Method of 50% Threshold Value

As the von Frey filaments, seven filaments giving different stimulationstrengths were used. The 50% threshold value was calculated according tothe up down method by referring to the method of Chaplan et al. (ChaplanS R, Bach F W, Pogrel J W, Chung J M, Yaksh T L.: Quantitativeassessment of tactile allodynia in the rat paw, J. Neurosci. Methods,53:55-63 (1994).

Evaluation Method and Results

The efficacy was evaluated by orally administering the compounds ofExamples 48 and 118 using an oral feeding needle to rats on the day 9after the modified Chung operation, and observing the influence on thepain threshold value determined by the von Frey filament test. As aresult, oral administration of 50 mg/kg of the compounds of Examples 48and 118 raised the pain threshold value of the diseased limb, and it wasobserved that there was a significant difference compared with theresult for the vehicle group.
